Two mismatched LAPD detectives - on-the-edge Martin Riggs (Mel Gibson) and 50-year-old family man Roger Murtaugh (Danny Glover) – are assigned to investigate a death that leads them to a heroin smuggling ring. The quintessential buddy-cop film, LETHAL WEAPON launched a hugely successful franchise, kick-starting Shane Black’s career as an action screenwriter and giving Gary Busey one of his juiciest roles as menacing heavy Joshua.
